Detailed Description

2M592 is an engine piston ring application for a broad set of domestic vehicles, including Chevrolet Astro, GMC Safari, Ford F-150, and Chevrolet C1500 platforms. The ring package combines a steel top ring, grey iron second ring, and a steel rail/stainless expander oil ring arrangement to address combustion sealing, oil control, and cylinder wall contact in rebuilds that require a standard 4.000-inch bore. The plasma moly top ring surface and chrome/phosphate treatments add material-specific wear characteristics that matter in high-mileage service and overhaul work. This part cross-references Monroe Shocks & Struts (e.g., 10446KX, 19229K) for the same application.

What It Is Used For

• Restoring compression loss caused by worn ring faces
• Reducing oil consumption from worn cylinder sealing surfaces
• Addressing blow-by in rebuilt or serviced engines
• Replacing worn piston rings during engine overhaul
• Supporting proper oil control in standard-bore cylinder assemblies

Installation Notes and Tips

Verify bore size, ring groove dimensions, and engine configuration before installation. Match the ring set to the cylinder bore and confirm the top, second, and oil ring positions during assembly. Clean ring grooves thoroughly and inspect cylinder walls for taper or scoring before final assembly. Fitment includes many Chevrolet and GMC truck and van applications, plus Ford and classic passenger-car platforms, so confirm the exact engine build against the listed application data before ordering.

Quality Assurance

The ring materials and surface treatments are specified for rebuild use, with a plasma moly top ring surface and treated second and oil ring components for consistent service characteristics. Part number 2M592 is listed across a broad application range for Chevrolet, GMC, Ford, Oldsmobile, and Pontiac engine builds.
